GeneralThis Standard covers requirements for manually operated metallic valves sizes NPS 1⁄2 through NPS 2, foroutdoor installation as gas shutoff valves at the end ofthe gas service line and before the gas regulator andmeter where the designated gauge pressure of the gaspiping system does not exceed 175 psi (12.1 bar). TheStandard applies to valves operated in a temperatureenvironment between −20°F and 150°F (−29°C and66°C).1.2 DesignThis Standard sets forth the minimum capabilities,characteristics, and properties that a valve at the timeof manufacture must possess in order to be consideredsuitable for use in gas piping systems. Details of designand manufacture (other than those stated in thisStandard, including such design and production teststhat will produce a valve that will have the requiredcapabilities to meet this Standard) remain the responsibility of the manufacturer.

Nonmandatory Appendix A Quality System Program iii FOREWORD The B16 Standards Committee was organized in the Spring of 1920 and held its organizational meeting on November 21 of that year The group operated as a Sectional Committee (later redesignated as a Standards Committee) under the authorization of the American Engineering Standards Committee [subsequently named American Standards Association, United States of America Standards Institute, and now, American National Standards Institute (ANSI)] Sponsors for the group were The American Society of Mechanical Engineers (ASME), Manufacturers Standardization Society of the Valve and Fittings Industry, and the Heating and Piping Contractors National Association (later the Mechanical Contractors Association of America) The American Gas Association (AGA) determined that standardization of gas shutoff valves used in distribution services was desirable and needed The AGA Task Committee on Standards for Valves and Shut-Offs was formed, and development work commenced in 1958 In 1968, it was determined that a more acceptable document would result if approval were gained from ANSI and to facilitate such action, the AGA Committee became Subcommittee No 13 of the B16 activity This Standard offers more performance requirements than has been customary in B16 standards It is expected that this will permit both manufacturers and users greater latitude in producing and using products made to this Standard Work was extremely slow as the group gradually developed the document in the desired format Its efforts were successful when, on July 18, 1973, final approval was granted by ANSI The revision incorporated some major revisions to the format In addition, the scope of the standard was clarified so that the standard could be applicable to all manually operated metallic gas valves for use in gas piping standards up to 125 psig The revised standard incorporated testing criteria for valves that could have a specific pressure rating within this pressure range This revision was made to clarify the fact that the standard is also applicable bars machined to the nominal iron pipe size diameter of the valve ends and firmly connected to the valve ends as a test assembly [When a threaded end valve is used, the bars shall be threaded with American Standard taper pipe threads (NPT) as described in ASME B1.20.1, coated with thread lubricant and tightened to 50% of the values specified in para 4.4.2, Table 2.] C p resistance yoke G p gas valve L p load S p 24 in (610 mm) span between points for load resistance Y p 12 in (305 mm) span between points of load application The valves, when in the full open position, shall meet the minimum gas flow as specified in Table A valve of each size and type shall be tested to verify that the pressure loss is not greater than that specified in Table The test shall be conducted using a technically recognized procedure such as that contained in ISA S75.02 The test fluid and type of test facility and instrumentation are at the discretion of the manufacturer and shall be fully described in their test records PRODUCTION TESTING Each valve shall be tested at the time of manufacture at a pressure of at least 1.5 times the pressure rating marked on the valve, according to the method of test for gas tightness in para 4.2 GENERAL NOTE: The bending moment,
